Management of Hypertensive Patients with Body Weakness

Assessment and Classification of Hypertension

A blood pressure of 140/90 mmHg represents mild hypertension or elevated blood pressure, not a hypertensive emergency or urgency, according to the European Society of Cardiology 1
Hypertensive emergencies are defined by severe BP elevation (typically >180/120 mmHg) with evidence of acute end-organ damage, as stated by the European Society of Cardiology 2

Normal saline bolus can be administered to maintain euvolemia in patients with hypertension who may be relatively hypovolemic, as recommended by the American Heart Association 3
For patients with body weakness but without signs of fluid overload, small boluses of normal saline (250-500 mL) can be appropriate, according to the Society for Immunotherapy of Cancer 4
In patients with hypotension due to various causes, normal saline boluses of 5-10 mL/kg are recommended, as suggested by the American Heart Association 5

Start with a small bolus of normal saline (250-500 mL) administered over 30-60 minutes, as recommended by the Society for Immunotherapy of Cancer 4
Monitor blood pressure response after the fluid bolus, as advised by the Society for Immunotherapy of Cancer 4
If the patient has no history of heart failure or renal disease, up to 1-2 L of normal saline may be administered if needed, according to the American Academy of Allergy, Asthma, and Immunology 6

Monitor vital signs including blood pressure, heart rate, and respiratory rate during fluid administration, as recommended by the Society for Immunotherapy of Cancer 4
Use caution in patients with congestive heart failure or chronic renal disease to prevent volume overload, as advised by the American Academy of Allergy, Asthma, and Immunology 6
Be vigilant for signs of worsening hypertension during fluid administration, though this is unlikely at the current BP level, according to the European Society of Cardiology 1

After addressing acute symptoms with fluid therapy, evaluate the patient for underlying causes of hypertension, as recommended by the European Society of Cardiology 1
Consider out-of-office BP measurement with ambulatory or home BP monitoring to confirm the diagnosis of hypertension, as suggested by the European Society of Cardiology 1
For long-term management, lifestyle modifications including sodium restriction, exercise, and weight management are recommended, according to the European Society of Cardiology 1
